PNEUMATIC TIRE.

Specification of Letters Patent.

Application filed September 11, 1914. Serial No. 861,252.

To all whom it may concern:

Be it known that 1, JOHN W. MOAKLER, a citizen of the United States, residing at East Worcester, in the county of Otsego and State of New York, have invented cer-.

tain new and useful Improvements in Pneumatic Tires, of which the following is a specification.

This invention relates to pneumatic tires usually made of rubber or rubber fabrics and compositions, and intended for use on automobile" wheels, but which may be employed as well on bicycles and other vehicles without material change of construction.

This invention consists in the production of a tire, the outward construction of which may be of any selected character or design, comprising a radial, annular web, usually elastic and compressible, arranged in the middle of the tire, and extending from the inside of the tread of the tire to the wheel rim upon which the web immediately bears as this invention is ordinarily constructed.

The object at this invention is to 'interpose an additional support in an inflated tire, directly between the tread of the tire and the wheel rim where the greater portion of the machine and load weight is taken up.

llt is also an object of this invention to provide arts of special arrangement and constructlon for accomplishing the purpose, including twin, inflated inner tubes acting to support the web at the sides, and to maintaln the distension of the tire in the customary manner, whereby it is believed tion is taken at t e point where the valves for the inner tubes are located. Fig. 2 is a cross-section of the tire at any other point. Fi 3 is a section lengthwise of the valvular evices, and of the recess in the web which those devices occupy. The section is indicated by the indirect broken line M of Fig. 1

Throughout the dmwings and tion the same letter refers to the same part. Considering the drawings, the wheel A has av metal face a upon which is a demountable wheel rim B engaging a tire C.

The lining D for the interior of the tire nected together by a body or bridge por-- tion G, provided with a middle air connection and having at its ends the legs H and Y as best shown in Fig. 3. The legs usually extend to the lower surface of the web 0), or,- more clearly, to that surface ofthe web resting immediately against the wheel rim B. A suitable recess J is formed in the web to receive the valvular devices,

and by way of the ducts 'Kand 7 air passes to the valves and to the inner tubes. Each of the valves is yieldingly seated by means ofa sprin L, and the casing of the valve has a bee M. When'the head M-and the end m of the body G of the valve-support are clampedtogether by means of the screw cap N, an airtight joint is made with a portion of the inner tube engaged as illustrated. It will be noted that the screw cap N and its fellow rest against thewheel rim B, and that the legs H and h of the body G extend to the mouth of the recess J in the web d, in other ,words, the legs'al'so extend to the rim B. As the wheel revolves those parts are sim ly pressed against the-rim, and they are not displaced or distorted in anymanner.

To operate thisinvention', it is necessary to introduce the inner tubes. It will be ob served that the bottom, or that portion of the lining D toward the center of the wheel, as best shown in Fig. 2, is open, and the tubes may be readily placed in position between the sides of the web and the lining D,

and the valvular devices arranged in the recess J of theweb provided for. them. In fact, the web and adord in practice Patented Nov. 16, 1915. I

a very convenient means for introducing explaine the nature of its operation, what I claim is 1. In a pneumatic tirefthe COlIlbiIlBJJlOIl with a wheel rim, of a casing, inner tubes arranged side by side within the said casing, and means for admitting air into the said tubes comprising tubular portions communicating with the tubes, and a bridge connected with and carrying the said tubular portions, the; said bridge, having flegs constructed and arranged to stand upon the said rim andlto support the-saidbridge.

2; In -a pneumatic tire, the combination with a casing, of twin inner tubes arranged side by side within the casing, the said casing "havin a m'rddle web .located between the said tu es and having aportion extending below the tubes and provided with a recess, and means for admitting air into the tubes comprising tubular portions communicating withthef tubes and a bridge located in the recessfof the said web and having legs at its ends, the'said tubular portions being mounted upon the said bridge.

' Intestimony whereof I aflix my signaturein' presence-of two witnesses.
